I just bought a 44" 17hp toro z master today. When i picked it up today from the dealer everything seemed fine. But, when i was unloading it off my trailer several things happened: 1. when i took it out of neutral it jumped and started going forward without moving the arms. I believe this is because the neutral position is a little off. 2.When i tried to go in reverse it moved very slowly and the control arms got stuck. 3.it was not responding well to the steering, it almost felt like i had to force the control arms forward or back. They were hard to move. Is there a way to adjust this or do i need to take it back to my dealer and have them fix it. Thanks for the help.
